20.500.12556/RUL-137284 Measuring the efficiency of reduction gearboxes for electric utility vehicles during specific driving cycles Meritev izkoristka reduktorjev električnih gospodarskih vozil med posebnimi voznimi cikli This paper presents the results and the procedure for measuring the efficiency of a single-speed reduction gearbox developed for an autonomous electric utility vehicle. The resulting efficiency of the gearbox was investigated on three different driving cycles, which were selected because their speed profiles most closely matched the expected use of the autonomous vehicle. The required torque for each cycle was obtained from simulations of the vehicle’s driving behaviour including its predicted mass and dimensional parameters after a given driving cycle. The results of this research represent the achieved efficiency and average power loss of the gearbox on each driving cycle. The resulting gearbox efficiency was around 50 % in the predominant areas of driving cycles. efficiency gearboxes powertrain electric vehicles driving cycle izkoristek menjalniki transmisija prenos moči električni pogon električna vozila vozni cikel true false true Angleški jezik Slovenski jezik Članek v reviji 2022-06-09 11:59:49 2022-06-09 11:59:50 2022-09-15 04:14:54 0000-00-00 00:00:00 2022 0 0 Str. 303-313 no. 5 Vol. 68 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-01-01 629 0039-2480 10.5545/sv-jme.2021.7437 110923523 Petr_..._-_Measuring_the_Efficiency_of_Reduction_Gearboxes_for_Electric_....pdf Petr_..._-_Measuring_the_Efficiency_of_Reduction_Gearboxes_for_Electric_....pdf 1 C0607C0D9E0FEB79D7629D28F9FE9D36 99a835df7685d64b16acf0aac3f23d7f9b3490dc247d1ab91cb90f890a1e1231 13d91c1b-e7db-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157195 https://www.sv-jme.eu/sl/article/measuring-the-efficiency-of-reduction-gearboxes-for-electric-utility-vehicles-during-specific-driving-cycles/ 1 bf5274c8-e7da-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=157194 Fakulteta za strojništvo Strojniški vestnik 0 0 0
